Abstract

L'invention concerne des systèmes de projection optique et des procédés associés pour imagerie par projection qui utilisent le décalage de la position d'image dans le temps afin de mitiger les taches. A titre d'exemple, les systèmes optiques comprennent un projecteur comportant une source de lumière, une lentille relai et au moins une lentille de projection pour projeter des images. La lentille relai ou la lentille de projection peuvent comprendre au moins un élément lentille capable de translation dans le temps de manière essentiellement orthogonale à l'axe optique du système optique. Selon une autre solution, la lentille de projection peut dans son intégralité être décalée dans le temps afin de réduire les taches. En outre, dans des modes de réalisation stéréoscopiques, deux lentilles de projection peuvent être utilisées, au moins un élément dans chaque lentille de projection étant mobile afin de décaler l'image dans les temps pour réduire les taches. De plus, une compensation électronique, comme un adressage électronique ou une distorsion d'image, pour le décalage d'image peut être utilisée afin de décaler l'image dans une direction opposée au décalage de diminution de taches en position.
